COLZ Color Palette Font and Size

I would like to change the font on the color palette for a specific histogram, but I am unable to determine the proper method. For other axis on can simply do the following:

This method does not work for TH2::GetZaxis(). I know I can set the label font code globally through the following, but this doesn’t even change the font on the color palette.

Why is this text/label different from the other axes?

It was not implemented. Now fixed in the trunk.
Thanks for reporting.

Which part was fixed? The part referring to gStyle or the part referring to TAxis::SetLabelFont()?

now you can do

hist->GetZaxis()->SetLabelFont(22)

Thank you.
